   They switch on/off during few cycles (allowing for a starting surge) and   
   run/don't run for many cycles, so the switching on & off only matters for   
   the overall load. The type of load does matter.

   Or they bill appearant power & the major users /want/ PF correction, Note   
   that if you use a lot of reactive power it adds to the current on the grid   
   and the power company still has to put in heavier wire, so it does cost   
   them /something/.

   But the clipping occurs with a relatively constant phase. It may create a   
   nasty current waveforms which can be a problem but that's not what power   
   factor refers to.
